Company information

Autonomous Systems

JT operates globally with the Autonomous System of AS8681.

All Autonomous Systems transited by the JT network are contained in the AS-SET (or AS-MACRO in RIPE-181 terminology) AS-JERSEYTELECOM which is stored in the RIPE Internet Routing Registry.

The preferred method of filter generation is to build them automatically from the AS-JERSEYTELECOM data stored in the global IRR.
